Medicine21 CardsCreated 1 day ago

This flashcard set explains how fluctuations in sex hormones—particularly estrogen and progesterone—affect seizure frequency in epilepsy, trigger menstrually related migraines, and influence immune activity in multiple sclerosis (MS). It highlights the role of estrogen in inflammatory responses and the protective shift seen during pregnancy.

Psychotherapy: 84b - Brain States and Coma

This flashcard set outlines different levels of impaired consciousness—obtundation, stupor, and coma—ranked from most to least responsive. It also defines brain death as a clinical diagnosis marked by the absence of all brainstem reflexes and purposeful responses, distinguishing it from states where minimal reflexive or autonomic functions may still occur.

Psychotherapy: Clinical Medicine

This flashcard set identifies and differentiates disorganized thought processes such as flight of ideas and loose associations, which are key indicators in diagnosing mental health conditions like mania and schizophrenia. It also situates these features within the thought process section of the mental status exam.

USMLE - Micro Viruses

Reassortment occurs when viruses with segmented genomes exchange genetic segments, creating new combinations. This can lead to rapid evolution, high-frequency recombination, and potentially global pandemics. A common example is the influenza virus.

USMLE - Reproduction Part 4

Cryptorchidism is the failure of one or both testes to descend into the scrotum, often seen in premature infants. It leads to impaired spermatogenesis due to higher abdominal temperatures but usually normal testosterone if unilateral. It is associated with an increased risk of germ cell tumors, and labs may show ↑ FSH, ↑ LH, ↓ inhibin B, and ↓ testosterone if bilateral.

USMLE - Reproduction Part 2

**Cleft Lip** is a congenital anomaly resulting from the **failure of fusion between the maxillary and medial nasal processes** during embryonic development. This defect affects the formation of the **primary palate**, leading to a gap or split in the upper lip, which may be unilateral or bilateral.

Which hormonal fluctuations are likely to affect seizure frequency in women with epilepsy?

(Increased estrogen:progesterone ratio)

An abrupt drop in estorgen levels may trigger…

  1. Epileptic seizures

  2. MS flares

  3. Menstrually related migraines

Menstrually related migraines

  • Rapid withdrawal of estrogen may trigger migraine

  • May happen just before menstrual period, postpartum, or perimenopause

How do sex hormones influence the course of MS?

Estrogen (E2) -> Th1 phenotype -> Inflammatory -> MS predisposition

Note: E3 estrogen released in pregnancy leads to Th2 phenotype, MS remission

How does progesterone influence epilepsy?

Progesterone increases seizure threshold

  • Potentiates GABA
    -> Increased general inhibition

What happens to migraine in pregnancy?

  • Migraines unusual in 1st and 2nd trimester

    • Estrogen slowly increasing

  • Increase during 3rd trimester, postpartum

    • Rapid withdrawal of estrogen

Valproic acid should be avoided in which population

Women of childbearing age

Find soemthing else to treat migraine or epilepsy in anyone who might have a child!!

Which AED is most affected by changes in drug metabolism during pregnancy?

Lamotrigine

  • Glucuronidation is facilitated by estrogen

  • -> Faster drug metabolism during pregnancy

Rapid withdrawal of which hormone is might trigger a migraine in a suceptible individual?

Estrogen

If a patient with MS needs a disease-modifying agent during pregnancy, which one should you use?

Glatimer acetate

BUT, avoid DMAs in pregnancy if possible; MS flares are liekly to decrease due to increased E3 estrogen

If a patient is having higher estrogen and lower progesterone, are they more or less likely to have seizures?

More likely

(More estrogen + less progesterone -> more seizures)

  • Estrogen (E2) -> more seizures

  • Progesterone -> fewer seizures

How does pregnancy affect MS?

Women with MS are likely to remit during pregnancy

  • E3 estrogen released in pregnancy

    • -> Th2 phenotype (less inflammatory, increased immune tolerance)

    • Fewer MS flares

What is the best mode of contraception for a young woman with migrain with aura?

IUD

(In general, seems like the best option for all people discussed in this lecture)

  • Combined oral contraceptive pills and migraine with aura both increase risk of stroke; together, result in 7x increased risk

What happens to migraine frequency during menopause?

  • More migraines during menopause as estrogen levels rapidly fall

  • Much lower frequency of migraines after menopause

    • Estrogen is lower, but at a steady state

Many AEDs are enzyme inducers - what are the implications for patients taking oral contraceptive pills?

Less bioavailability of OCPs

Notably, OCPs also decrease bioavailability of lamotrigine

  • Recommend IUD, depo-provera, or condoms

Which hormone is associated with decreased MS flares during pregnancy?


Estriol (E3)

Most acitve during 3rd trimester

How does seizure frequency change during pregnancy?

Post-partum period?

  • Stays the same in pregnancy

  • Increases post-partum

Which agents are used for abortive migraine management during pregnancy?

  • 1st line

    • Non-pharmacologic (cold compress)

    • Acetaminophin

  • 2nd line

    • NSAID - 1st and 2nd trimester only!!

    • Metoclopramide

  • 3rd line

    • Sumatriptan (1st line when not pregnant!)

  • DO NOT USE BARBITUATES, ERGOT, DHE

What agents are used for prophylactic migraine treatment in pregnancy?

Usually not indicated during pregnacy - migraine frequencey decreases due to steadily inreasing estogen

If anything, use:

  • 1st line: Mg

  • 2nd line: Metoprolol, propranolol

    • Stop a few days before delivery

  • 3rd line: verapamil, TCAs, SSRI, SNRI

  • DO NOT GIVE VALPROIC ACID OR TOPIRAMATE

How does estrogen (E2) influence epilepsy?


Estrogen (E2) lowers the seizure threshold

  • Potentiates Glutamate

    • -> Excitation

  • Inhibits GABA

    • -> Decreased inhibiton

Which anti-seizure drug carries the highest risk of major congenital malformation?

Valproic acid

Also associated with lower IQ, increased risk of Autism

Better option = Lamotrigine

Which medication for MS takes up to 2 years to wash out and is FDA pregnancy class X?

Teriflunamide

  • Persists in sperm too!
